i To all whom it may concern:

Be it known that I, EDGAR B. S'rocKrNe, a citizen of the United States, residing at lVashin'gton, in the District of Columbia, have invented certain new and useful 'Improvements in Mechanical Starters for Automobiles, of which the following is a specification, reference being had therein to the accompanying drawings,

This inve tionrelates to certain newand useful impr vements in mechanical starters for automobiles; and has for its object, the provision of a starter by means of which the engine can be set in motion by the driver from the seat of the automobile by operating a lever located adjacent the seat.

Another object of the invention is to pro vide a starter'which can be readily placed in position in an automobile withoutchanging the construction in any way. or moving any of the parts; the same bemg arranged ad acent the engine shaft and having an operating'member adapted to cooperate with.

a member carried by the engine shaft and fitted to mesh with the operating member when brought into engagement therewith'by the operation of the treadle.

Another object of the invention is to provide a starter which can be placed in position upon an automobile and operated without interfering with the use of the ordinary starting crank in any way.

Another object of the invention is to provide a starter somounted that, when in inoperative position, it will be held firmly therein so that it is impossible for the same to beaccidentally thrown into engagement with the engine shaft by the jolting of the car.

A. still further object of the invention is to provide a starter member in the form of a gear carried by a hanger and adapted to intersect the path of travel of a cooperting gear carried by the engine shaft when the lever adjacent the seat is operated;

Another object of the invention is to provide means for automatically throwing out of'mesh, the gear of the engine shaft and the gear of the starter upon a complete revolution of said shaft, or upon the back firing of the engine causing a back kick, whereby a starter is provided which auto.- matically prevents accidental in ury when used by an inexperienced or a careless operator.

Another and still further object, of the invention is to provide n'ovel means for lookng the operating or starting member per 86 brought to bear upon the operating lever, or it may be a treadle, which automatically releases the operating or starting member and allows the same to be drawn down into engagement Wlth the gear of the engineshaft and then rotated; means also being provided for preventing the rotation of the operating member until it has intersected the path of travel of the gear of the engine shaft and engaged therewith, so as to pro vent any loss of rotary motion. I

-.A still further object of the invention is 1n inoperative position until pressure is .to provide a starter which is automatic in operation in respect to the returning of'the contact with the driven member on the engine shaft.

Another and further object of the inven-v tion is to provide positive means for throwing the operative member out of engagement with the member of the engine shaft after the same has made a complete revolution; means also being provided for automatically locking said member in inoperativeposition so as to allow the spring of the operating member to rewind an operating cable thereon after the treadle has been released. Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims. I

In the drawingsFigure 1, is a top plan view of an automobile showing the application of my improved construction of mechanical starter; Fig. 2,.is a side elevation of an automobile showing the mechanical starter in position in dotted lines; Fig. 3, is an elevation of the starter and supporting plate, showing the starter in itsv locked, inoperative position ready to be operated by the pressing of. a treadle; Fig. 4, is a similar view showing the operating member thrown into mesh with a gear on the engine shaft by pressing upon a treadle, said operating member being held from rotating by a pin and hook in order to prevent the rotation of the operating member before it has intersected the path of travel of the gear of the engine shaft; Fig. 5, IS a s milar new showing the operating member completing its erative position and locked, during the return movement of the. lever or treadle; said operating member being free to rotate to rewind the operating cable thereon; Fig. 7,

. is a side elevation of the starter showing the gear and coupllng member of the shaft in' section and the ordinary startingcrank in position to'start the engine, the mechanical starter-being also in position to start the engine. TlllS view shows that either the mechanical or the crank starter can be'used without interfering with one another; Fig. 8, is a detail elevation showing a slightly modified form of means for spring-actuating the operating member; Fig. 9, is a top plan of the same; Fig. 10, is a detail section through the operating member; and Fig. 11, is a detail of a slightly modified form of cam and hanger. i

Like numerals of reference refer to like parts in the several figures of the drawings.

In the drawings, 1 have shown a mechhnical starter especially constructed to be used in connection with a Ford machine, but it is of course understood that the same can be adapted to be used in connection with any of the well-known makes of automo biles now in use and comprises a supporting plate 1 adapted to span the engine shaft 2 having brackets 3 at its ends for securing the sameto the side bars 4 of the automobile frame which is one way of mounting the supporting plate, and it is of course understood that various other means can be employed for connecting the plate to the frame or for supporting the plate in the desired position. By connecting the plate such a position that the operating parts carried thereby which will be later described, will not interfere with any of the mechanism of the automobile to which 1t is applied.

The plate 1 is provided with an upwardly projecting extension 5 to one side of the fan shaft on which plate is a hanger 6 pivotally mounted upon a bearing stud '7 and secured in position thereon, preferably. by cotter pins, as clearly shown. Said hanger comprises a pair of spaced side members 8 having as here shown, a mutilated gear 9 mounted between the same upon a bearing pin 10 which. projects into a groove or slot 1]. formed in the supporting plate 1 in order to limit themovement of the hanger in either direction, as will be later described.

The mutilated gear is provided with a groove 12 in this instance formed ,midway Qofits width in order to economize space laterally Which isusually limited by the juxtaposition of the fan and the belt. In the groove 12, is seated an operating cable 13' fastened as shown at 14 and extending .sidewise over the engine shaft around a guide pulley 15 and then rearwardly under the body of the vehicle and over a guide pulley 16.

Pivotally mounted within the automobile under" the steering wheel and adjacent the seat thereof, is a treadle 17 preferably mounted in a bearing 18 arrangedupon the floor of the automobile; said treadle having a 'foot portion 19 which can be readily ma nipulated by the foot of the driver by pressing forwardly and downwardly, thereon. The treadle 17 is provided with a depending arm 20 bifurcated atits lower end in which is revolubly mountedja groove pulley 21 over which the cable 13 passes, and

said cable is brought back and has its free end secured as shown at 22. By connecting the operating cable and mounting the same in this manner, themovement ofthe treadle is reduced in order to obtain the desired distance of travel of the arm 20 to cause the operating gear to make a suflicient portion of a complete revolution to give the engine shaft a complete revolution, as will be hereinafter fully described. The diameter of the operating'gear relative to the gear on the engine shaft.- determines the leverage; the larger the diameter the greater the leverage and the lesser the portion of a-complete revolution required to 'secure a complete revolution of the engine shaft.

One face of the gear 9 is provided with a pocket 23 .in which is seateda helical spring 24: having one end connected to the wall of the pocket as shown at 25 and the other end is connected to apin 26 carried by one of the side bars of the hanger in such a manner that when the cable is operated, the spring will be. wound and this spring is preferably placed under tension when the. gear is in inoperative position so that after thetreadle has been operated and the same is *released, the gear will be vrestored to its original position. I In order to provide means forautomatically returning the operating gear to its normal inoperative position after the same has been operated tostart the engine, I provide the gear with a pin 27 extending trans versely therethrough; the projecting end 28 thereof, co-acting with a cam 29 secured to the plate 1 in'such a position that when the hanger is moved with the gear in position'to start. the engine, the cam will only be engaged by the projecting end of the pin on the final movement of the operating gear so as to throw the same back into its in position therein by cotter pins 42.

normal, inoperative position, after it has performed its function of starting the engine shaft. This cam may be provided with a hooked upper end 30 to limit the movement of the pin carried by ,the gear, in which respect the hooked end forms a stop in addition to those formed by the groove 11 in the plate 1. This hooked end may therefore, be omitted as shown in Fig. 11. i The opposite -end-31 of the pin 27 co-acts with a spring finger 32 of ahook 33 pivotally mounted on the hanger as shown at 34, said hook co-acting with a pin 35 fixed to the projection 5 of the plate 1 in such a position that on the final movement of the operating gear, the pin 27 of the same co-acting with the cam, will throw the hanger back into its original position and the hook will engage the pin and lock the hanger in that position; said hook being held under spring tension by a flat spring 36 carried by a stud 37 mounted upon the hanger. i

As shown inFigs. 1, 2, 3 and 4, upon the movement of the cable by the treadle, the hook is first released in order to allow the hanger to swing upon its bearing until the operating-member carried thereby is in position to rotate the engine shaft, whereby increased pressure being brought to bear upon the operating member through the medium of the cable, the projecting end 31 of the pin 27 will ride off of the spring finger 32 so as to release the operating gear and allow the same to rotate.- Upon the return movement of the operating member after the treadle has been released, the projecting end 31 of the pin 27 rides under the spring finger to a position to release the hook in a subsequent operation. The hook beingover the pin 35, the operating member will be securely held in inoperative position so as to prevent any danger of the same being accidentall} thrown in the path of travel of the cooperating member of the engine shaft. It will be noted that when the operating member is in mesh with the engine shaft gear,the end of the hook 33 bears against the pin 35 and tends to keep both gears in mesh.

In fitting the engine shaft to cooperate with the movable starting member, I provide a clutch cup 38 with a gear 39, (which may or may not be grooved for the reception of the cable), carried by a sleeve 40 extending into the clutch cup and securely fastened therein by the clutch pin 41 which is hggld 3 this manner of fitting the engine shaft to cooperate with the starting member, the construction of clutch member now in use upon automobiles is not changed and the gear is attached thereto in such a manner that the clutch head 43. ,of the starting crank shaft 4.4L has free movement within the same whereby a mechanical starter is provided which does not interfere with the operation of the crank starter now in use on automobiles. This enables the engine to be'started either by the mechanical starter or the crank crank shaft are of the shape shown, a space is provided to receive the sleeve of the gear.

As shown in Fig. 7, a flange 45 may be provided for the gear of the engine shaft; this being omitted in Figs. 3, 4:. 5 and 6 in order to show the gear in full lines and theflange in these figures, is shown in dotted lines.

In the modification shown in Figs. 8, 9 and 10, instead of providing the operating gear 46 with a helical spring, I form the same with a groove in which is arranged a cable 47, having one end extending over a guide pulley 48 mounted in the supporting plate and connected. to a coil spring 49; the other end of saidcable extending in the opposite direction to the operating treadle and said cable is fastened within the grooves preferablyby a staple 50 after being wound once around the same, and this construction is illustrated in order to show that other forms of springs than one arranged on or in the operating gear, can be used. Both forms of spring perform the functions of returning the hanger, carrying the operating gear, rewinding the cable to its original position in connection with the spring 24, and locking the parts in said position. v

In the modification shown in Fig. 11, the hook 39 of the cam 29 is dispensed with, which formed a stop for the hanger and the side bar of the hanger adjacent the plate is notched as shown at 51 and the cam 52 is extended as shown at 53 in such a manner that all danger of the cooperatingpin car.-

ried by the operating gear riding past the end of the cam is dispensed with and a positive movement is given to the hanger toinsure the hook engaging the pin so as to lock" the hanger in inoperative position. i .i

In the operation of a mechanical starter constructed asherein shown and described, assuming that the starting member is in the position shown in Fig. 3 and locked by the hook, upon pressurefbeing placed upon the treadle by the operators foot, the cable will start the gear to rotate slightly so as to disengage the hook from the retaining pin which releases the hanger j'jand allovvs"the; same to bedrawn down into mesh with the I gear of the engine shaft; the projecting end 31 or the pin 27. co-acting'with the spring fin er 32 which prevents the gear. from ro tatmg within the hanger toany material extent, until the coiiperating gears are-1n mesh, whereupon a continuous pressure be ing brought to bear upon the treadle, the

gear starts to rotate against the tension of jecting end 28 of the pin 27 comes into contact with the cam 29 which'is of such a shape the spring carrying with'it the gear'of the engine shaft and as the size of the operating gear is greater than the engine shaft, a complete revolution will be given to the engine shaft by a partial revolution of the operating gear so as toinsure the starting of the engine. While I have shown a mutilated gear, it is-of course understood that a com-v plete gear will operate and accomplish the same result; as is illustrated in Figs. 8, 9 and 10.

As the operating gear rotates, the pro that it fails to act until the last teeth of .the mutilated gear have engaged the teeth 30 braces the pin SO as to hold the hanger -in of the gear of theengine shaft at whichtime, the pin rides upon the operating por-.

tion of the cam which-throws the hanger back into its original position, carrying with 1t, th e.gear and as the spring hook engages thelfpin 1t rides over the same and emthe position shown in Fig. 1 with the teeth of the cooperating gears out of mesh. l/Vhen the treadle is released by the operator, the

operating gear being out of mesh with the gear of the engine shaft and the spring wound by the operation of the treadle, the spring starts the -gear to rotating in a re- 1 verse direction, so as't'o rewind the cable thereon, and as the projecting end 31 of the pin comes mto engagement with the spring finger 32 1t rides under the same and as sumes the position as shown in Fig. l, in

which position the operating. gear is securely locked in inoperative. position ready to be again operated by the manipulation of the tr'eadle.

From this description, it will be-seen that the'spring not only rewinds the cable upon the operating gear, but also through the medium of the cams, pins and hook, automatically returns the hanger carrying the same to its original position and locks the same in that position.

By arranging the operating gear to one side of the gear-of the engine Shaft, if a back kick of the engine occurs, the hanger will be free to move in the direction of retation of the engine shaft gear so as to throw the'gears out of mesh, thereby preventing any injury being done to the op'er-- ator or to the starting mechanism. On the other hand, if the engine should be started before 'a Complete revolution is given to the engine shaft, the operating gear being rotated thereby, would throughthemedium of the pin co-acting with the cam, throw the operating gear. out of mesh therewith. -Wh1'le I haveshown and described certain ',;details of construction in connection with my'mechanical starter and manner of mounting the samein the frame of an automobile, I'wish' lt lZO be understood that the manner of supporting the same and connecting the powertransmittin'g elements such as the treadle and cahle,may be varied to adapt the starter to automobiles of various makes without departing from the scope of my invention. These details are not essential, as the main object of this invention is to provide "a mechanical starter mounted to intersect the path of-travel ofthe'gear of the engine shaft in suchia manner that it will be automatically thrown out of engagement therewith by the. rotation of the engine shaft in either direction: In case the first of a series of cylinders of the engine is actuatedby an explosion therein, the engine in its faster rotation completes the action of the starting member and of the .treadle and also returns the hanger to its inopera tive position automaticallyand after this operation of the engine, the spring in winding up the cable. throws the treadle, which has been suddenly advanced by the engine, back against the foot of the operator, but without injurious force and ,when the foot is withdrawn, it completes the winding of thecable, the hanger in the meantime, being locked in inoperative position.

I ,am aware that various forms of mechanical starters are in use, but in each in stance, the starting mechanism is not completely thrown. out of operation when not in use, and in no instance am I aware that a starter has been provided which can be placed in position upon the automobile with out interferingviith the cranking mechanism now in use.- a

While- I have shown and described the movable startingmember cooperating with a fixed member carried by'the engine shaft,

it is of course understood that-the movable starting member would operate a. movable member carried by the cngmeshaft in substantially the same way, and I do not wish starter in connection with a fixed cooperatout of the path of said fixed member isi held in inoperative position in such a manner that it is practically impossible for the same to be-accidentally thrown into inoperative-position without operating the treadle.

In the drawings forming part of this application, I'have shown the plate 1 connected to the frameof the vehicle by brackets 3 which are bolted to the side bars ofthe frame asshown inI igs. 3, 4,5 and 6, and
